In addition to the budget and quality of decoration, the environmental protection issue is also the focus of attention. Recently, the malignant incident caused by the decoration pollution of the newspapers has caused people to have to put environmental protection in mind. After the renovation project is over, we need to test the indoor environment to see if it meets the safety standards. But how do you detect it? Is it necessary to ask a professional testing agency? Or can you test it yourself, but is the data reliable? The following is a common way to describe pollution detection for decoration. 1, self-awareness

When the home decoration is over, if the whole family has low immunity, energy drops, fatigue, etc. At the same time, it feels pungent odor, especially when approaching a certain furniture, it will cause tears, etc. And keep the room well ventilated. Of course, we do not want everyone to do so. It is advisable to have a good stay after a certain period of time after the renovation.

2, animal and plant reactions

Animals and plants live in the same space as humans. It depends on how animals and plants respond. If the animal experiences a drop in activity, illness, dead plants, yellowing, etc. after living in a new home, it indicates that the environmental index of the new home is unqualified, and the pollution may endanger people's health.

3, simple self-test box

Formaldehyde self-test box is the easiest and easiest to use method for self-testing. The self-test box is similar to a ph test paper, and the value of a formaldehyde is obtained by comparing the colors. If the test liquid is blue, it is a sign of exceeding the standard. At this time, a professional company should be found as soon as possible to carry out indoor pollution detection and take further measures.

4, physical and chemical detection method

This method of detection is the most sophisticated, and third-party testing companies generally use this method, and ordinary people are unable to use it. Detection methods include: AHMT spectrophotometry, phenol reagent spectrophotometry, gas chromatography electrochemical, sensor method, which we all know.

5, there is a third party testing agency

In addition to the above methods, it is also possible to find a third-party inspection company to issue relevant test results after the test and take further measures.

The above are several methods commonly used in indoor environment detection, which can generally be tested from the side to see if the indoor environment at home is qualified. However, if you want accurate and secure data, you should still find a professional testing agency. We still have to believe in science.

Narrow Bandpass Filter

narrow bandpass filters are characterized by high passband transmittance, accurate center wavelength, steep filter edges between pass- and blockband, and broadband blocking range.In manifold applications, the filters are used to select the appropriate part of the spectrum either from a light source or in front of a photodetector.Narrow bandpass filters for biomedical and industrial applications, with FWHM from 10nm to 60nm

Optical Bandpass Filters are used to selectively transmit a portion of the spectrum while rejecting all other wavelengths. Optical
Bandpass Filters are ideal for a variety of applications, such as fluorescence microscopy, spectroscopy, clinical chemistry, or imaging. These filters are typically used in the life science, industrial, or R&D industries.

IR Narrow Bandpass can use by Fluorescence analyzer, enzyme marker, cable TV upgrade equipment, wireless transmission equipment, mobile phone barcode scanning, infrared electronic whiteboard, infrared camera, infrared touch screen, iris recognition, infrared medical equipment, infrared ink recognition, red film recognition, face recognition sensor system. Hand held infrared laser rangefinder, laser rangefinder, optical instruments, medical and health equipment and testing instruments.
